For some reason when I bake my banana bread it doesn't want to get done. I bake it at 350 for atleast an hour and my toothpick doesn't come clean and there are undone parts in the middle when we eat it. Does anyone have any suggestions?

I would say you aren't baking it long enough. You could also try to not fill your loaf pan so full. Save some of the batter and put it in muffin pans. That way you won't burn the top and bottom before cooking the middle of the loaf.
